TRUCK FOR DRYING POTTERY, ETC.

Application filed April 3,

To all whom it may concern:

Be it known that I, THOMAS H. RHoAns, a citizen of the United States,residing in Philadelphia, Pennsylvania, have invented certainImprovements in Trucks for Drying Pottery, Etc, of which the followingis a specification. y

The object of this invention is to provide an apparatus for drying largepieces of clay, such as tank blocks, so that the drying will be from thebottom upwards, the drying of the upper portion being delayed so as topre vent cracking and warping of the article.

In the accompanying drawings:

Fig. 1 is a perspective View, showing my improved apparatus for dryinglarge pieces of clay mounted on a truck;

Fig. 2 is a longitudinal sectional view;

Fig. 3 is a transverse sectional view; and

Fig. 4 is a sectional view on the line 4: c,

Fig. 3.

Referring to the'drawings, 1 is the frame of the truck having boxes 2for the axles on which the flanged wheels 3 are mounted. These wheelsare adapted to travel on a track in a drier of any suitable type. Eachcorner of the frame has a rectangular opening 4. 5 designates a trayhaving four posts 6, in the present instance. At the bottom of each postis a tapered pin 7 adapted-to the openings 4: in the frame. In the upperend of each post is a socket 8 adapted to receive the pins 7 of an uppertray 5, which is placed on top of the lower tray, as clearly shown inthe drawings. Connecting the posts are cross bars 9 and longitudinalbars 10. Mounted on the bars 9 is a series of slats 11, which are spaceda given distance apart, as clearly shown Fig. 3, so as to supportproperly the articles a being dried. Mounted on each tray is a cover12having a body portion 13 that extends over the article being dried anddeep flanges 14, which preferably extend to a point below the uppersurface of the slats 11.

In the corner of each cover 12 are openings 15 for the passage of thepins '7 of an 1923. Serial No. 629,715.

upper tray. By this arrangement, a series of trays can .be mounted, oneupon the other, the pins holding the trays in alignment and preventingthe trays shifting during the movement of the truck through the drier.

By this construction, it will be seen that heated air must pass underthe covers and up between the slats lltso as to dry the clay bodiessupported by the slats, the drying being from the bottom upwards. Theupper portions of the clay bodies are protected by the cover,consequently, the articles are dried without checking or cracking.

W'hile the invention is illustrated as mounted on a truck, it will beunderstood that the trays may be mounted on any suitable carrier, orthey may be mounted in a stationary position, the heated air being freeto circulate around the trays.

I laim:

1. The combination of a tray having slats thereon to support thearticles to be dried; and a flanged cover extending over the articlesand to a point at, or near, the upper surface of the tray, so thatheated air, in circulation, will pass up between the slats and the upperportions of the articles will be protected.

2. The combination of a series of trays, one mounted above another, oneof said trays having pins adapted to rest in another tray; and a coveron each tray having deep flanges, the covers being perforated for thepassage of the pins.

3. The combination in apparatus for dry in'g clay bodies, of a series oftrays, each tray having posts and supporting slats on which the articlesto be dried are mounted, each post having a pin at one end and a socketat the opposite end; and a cover for each tray supported by the posts,said GOV. ers having deep flanges extending to point near the uppersurface of the slats so as to cause the heated air to pass under thearticles being dried.
